We paired the Brownells BRN-4 HK416-style upper with the STS416 A1 lower to create a faithful HK416 clone in 5.56 NATO, then shot drills to see how the short-stroke piston system handles recoil, reliability, and balance.<\/p>\n\n\n\n

M4 vs HK416: Why the Short-Stroke Piston 5.56 Matters for Clones<\/strong><\/h2>\n\n\n\n

The HK416 is one of those iconic AR-15s that has become legendary due to its use by Tier 1 groups across the globe. Ask Delta Force about the HK416, a Navy SEAL, or Osama bin Laden<\/a>. Oh, wait. You can\u2019t. They will tell you the HK416 rifle is built like a tank. Owning a real, bona fide HK416 is expensive. Building a clone is a route you can take, but be forewarned, building an HK416 clone is easy; deciding what HK416 variant you want and how close you want it to an original can send you down a rabbit hole.<\/p>\n\n\n\n

I made it easy and opted for a Brownells complete upper and an STS lower to build an HK416 that performs and looks like an original.<\/p>\n\n\n\n
